Abstract

There is provided a rigid container, comprising: a vessel having an inner surface; a cap having an underside; a first film substantially covering the inner surface of said vessel; and a second film on the underside of said cap, wherein said first and second coatings are substantially non-porous and have a Shore A durometer measurement of 10-90. There is also provided a method for making sound-dampened container, comprising: forming by blow molding a vessel having an inner surface comprising at least one polymer; coating the inner surface of said vessel form a film with a thickness of at least one silicone rubber; and curing said film at a temperature for a period of time to form a cured film with a Shore A durometer measurement of 10-90.
